In a video, Franklin Chang-Díaz said "the only problem is the temperature". And it is logical that with electricity outer space, you can not create so much temperature.

In addition, you have to beat the cold of the universe.

You must of missed the news that Mr Higgs got his Noble prize this year because the guys and gals at CERN managed to bang particles together at temperatures that were only found during the first fractions of a second of the universe in a circular ring of quite hard vacuum. Some of the vasimir stuff is quite cold and low energy in comparison.

Um.. no. Vacuum makes a very nice insulator. It is quite easy to get stuff quite hot because they only way for matter to get rid of it is by radiation, which is a problem because there is so much of it. Gas and dust in the "cold" of interstellar space is often tens of thousands of degrees, and in places up to millions of degrees.

Antagonizing a plasma to ridiculous temperatures is not hard at all. It doesn't even take that much energy to do because the mass you are heating is very low.
